Abstract

A quantitative analysis of the correlation between the technological properties of cubic boron nitride (cubonite) grinding powders, modified with a combined coating, and the performance characteristics of grinding wheels made with such powders has been conducted. The values of the paired correlation coefficients were obtained between the relative loss of abrasive and the surface roughness (parameter Ra) of the treated surface (dependent factors), the technological parameters of the coating, the processing efficiency, and certain morphometric characteristics and technological properties of the modified grinding powders (independent factors). Factors exerting the greatest effect on the relative consumption of cubonite grinding powder in wheels during grinding are the processing efficiency (correlation coefficient of 0.884) and certain morphometric characteristics, such as the roughness of the grain projection (correlation coefficient of 0.28 and 0.294). In the case of surface roughness (parameter Ra), the most significant factors are also the processing efficiency, with a correlation coefficient of 0.856, and the specific perimeter of the grain projection, with a correlation coefficient of 0.12. Recommendations for applying these results are presented.

复合涂层长石磨粉的工艺性能与复合涂层制砂轮性能的相关性研究

定量分析了复合涂层改性立方氮化硼（cubonite）磨削粉的工艺性能与用复合涂层改性立方氮化硼（cubonite）磨削粉制成的砂轮性能之间的相关性。得到了磨料的相对损耗与处理表面粗糙度（参数Ra）（依赖因素）、涂层工艺参数、加工效率以及改性磨粉的某些形貌特征和工艺性能（独立因素）之间的配对相关系数值。磨削过程中对砂轮中立方石磨粉相对消耗影响最大的因素是加工效率（相关系数为0.884）和某些形貌特征，如晶粒投影的粗糙度（相关系数为0.28和0.294）。对于表面粗糙度（参数Ra），最显著的影响因素也是加工效率，相关系数为0.856，以及颗粒投影的比周长，相关系数为0.12。提出了应用这些结果的建议。
